When the CCF is activated, the dev->parent is not necessary
the reference to SCMI transport and the function devm_scmi_of_get_channel
failed for the registered SCMI clock, child for protocol@14,
the channel is null and the SCMI clock driver crash for any operations.

This patch changes the first parameter of the ops of_get_channel(),
aligned with other process_msg() to pass directly the good reference,
i.e. parent result of find_scmi_transport_device(dev)
which return the reference of the scmi transport device.

To check dynamic loading of config object, currently APU_0 is used.
Suggestion from pmwfw team is to load OCM_BANK_0 and check for
XST_PM_NO_ACCESS error only to skip future config objects. Other errors
should not be considered for skipping. Change from NODE_APU_0 to
NODE_OCM_BANK_0 and check for XST_PM_NO_ACCESS to skip future config
objects.

Add ":  " to printf statement when there is no permission to load config
object, to align with PMUFW version print.

Update kernel doc for return value for zynqmp_pmufw_load_config_object().

This function is also available as ofnode_is_enabled(), so use that
instead.

We can check if the message was acknowledged in the common
ti_sci_do_xfer() which lets us remove it from after each call to this
function. This simplifies the code and reduces binary size.

The inline hint is not needed here, the compiler will do the right thing
based on if we are compiling for speed or for code size. In this case the
inline causes this function to be placed inside each callsite which is
not the right thing to do for either speed nor size. There is no
performance benefit to this due to the larger function size reducing
cache locality, but there is a huge size penalty. Remove inline keyword.

We don't need to print the same message in every location, just
print it in the function that fails and remove all the extra
message printouts.

This ti_sci_do_xfer() function already prints out the reason for the
failure, and the caller of each of these functions should also notify
the user of the failed task. Remove this extra level of error message.

Try loading pmufw config overlay for core0, if it doesn't return any
error it means pmufw is accepting nodes for other IP's. Otherwise dont
try to load config object for any other IP, just return from
zynqmp_pmufw_node function.

zynqmp_pmufw_load_config_object() has some error cases and it is better
to return those errors. Change prototype of this function to return
errors.
